Classic weekend Bart pattern. I honestly cannot say I am surprised, I was actually expecting it. We had the same over a weekend not long ago and I knew after the pump towards the 12K mark was going to retrace, shorted it for a small PnL but was not enough, I should have waited longer and I would have caught the Bart drop. Up around these price levels we will have people taking profits and some miners capitulating at a higher price. I would not rule out another higher end pump followed by another dump for some to take profits at the highest level possible.
Be careful trading this market and ALWAYS use a stop. Don't get REKT!
